Had surgery for one myself in November, followed by shoulder surgery in December. Happy holidays...
Needless to say, my return to activity has been slow and gradual. I've been running (I'm an endurance athlete) since mid-January off and on, and I have lifted the last three weeks, but haven't squatted anything over 100 lbs. Just trying to retrain the movement. Then, two days ago, not immediately following a workout or a toilet trip, the area where I was injured before started hurting like hell. It's since gotten worse, perhaps related to my running yesterday. Still, even with the morning off, it hurts today, and the pain seems to include the area around my stitches now, too.
I have no bulge anywhere, but I didn't the first time around either, so I'm nervous and a bit pissed. I had the mesh put in, and the doc said I was good to go for any and all activity, but I've been careful. I'm hoping for a good diagnosis next Tuesday when I get in to see the doc.
Bottom line: take it easy and see a doc, because hernias seem to be pesky little bastards out to kill your athletic efforts.
